We have made a complete list of roofing options available in India. </p><p><br></p><p><strong>1.Traditional Clay Roof tiles</strong></p><p>Traditional Roof tiles have been in the market for several decades. The high maintenance and less aesthetic appeal have reduced their popularity and caused them to fade away from the main stream. Even-though they are not so preferred in the recent years, there are still vendors selling these tiles. The main problem with these tiles are their inability to resist weather changes, algae and Fungus. Since they are plain mud clay, the water absorption of these tiles are comparatively more than others. Their colour is also prone to change over time. The strength of these tiles are also very low and can cause a lot of damage in the time of laying.</p><p><br></p><p><strong>2.Red Clay Roof tile</strong></p><p>These are similar to the traditional roof tiles, actually made from red clay tiles. They are of two kinds – Tiles with colour coating and the tiles without coating. The tiles without coating are usually imported from other countries with various profiles. They looks bulky and elegant, and are usually expensive. They are generally imported from Spain, Portugal, Malaysia, Indonesia, US etc and are prone to algae and fungus. </p><p><br></p><p>There are also some roofers who markets red clay roofings with quality colour coating, similar to that in white clay roof tiles. These are also usually expensive than the white clay tiles, but comes only in a few popular profiles. These are high quality tiles but less popular due to the scarcity in selection.</p><p><br></p><p><strong>3.Concrete roof tiles</strong></p><p>These tiles were popular for some time, due to the availability of different colours. They comes in different colours and profiles. But they were highly criticised and discouraged by everyone in the industry during the course of time. The main reason includes their heavy weight, need for much more stronger truss works, Water leakage and fading colours. But they are still being sold in the market by several manufacturers and the wide selection of colours attract customers to these tiles. This tiles also adds more heat inside the house, defeating one of the core purpose of using roof tiles, since it is made of concrete. These are exposed to the rain water and sunlight and cracks, leakage and algae are a common story for these tiles. All these reduces its reliability and efficiency, but still the aesthetics force some people to give it a try.</p><p><br></p><p><strong>4.Chinese ceramic roof tiles</strong></p><p><strong>Chinese ceramic roof tiles</strong> are actually the second quality white clay roof tiles imported from china. They are a cheaper form of the normal ceramic white clay roofing tiles and inherits most of its features. The colour coating, load bearing capacity, resistance to environment etc are also claimed by these tiles also. They are aesthetically pleasing and looks better than concrete roof tiles. They also are highly durable and colour coating is better than concrete roof tiles in the market. The white clay and <a href="https://www.chinasinograce.com/building-materials" rel="noopener noreferrer" target="_blank"><strong>ceramic coating</strong></a> gives it better colour coating than the red clay models and also provide weather resistance.Unlike the first quality tiles, these roofing tiles will be only having a single colour coating and the content of porcelain will be very low, resulting in a lower finishing than the later.</p>
